A resume is one of the most important parts of an interview process. We have never been formally taught how to make a CV, so we make do with templates on the internet or rely on mentors to guide us. So what is the universally accepted and ideal way of presenting my curriculum vitae?

Trim unnecessary details out of CV, like Hobbies or interestes (if irrelevant to the the job)

Keeping a uniform font size and alignment throughout your CV

Instead of Verbose, write down very crisp sentences

If you have work-ex, try to quantify your work. E.g. Say you have organised training sessions for your team-mates; You write down about its impacts like how many team-mates trained, number of hours and amount of money you’ve saved for your firm by doing that
